1 General information
This operating and installation manual contains all the information on the installation,
commissioning and operation of the following weighing platforms.
• PUA574 as a coated design
• PUA579 as a stainless version
approved for use in hazardous areas of Zones 2/22
• PUA579x as a stainless version
approved for use in hazardous areas of Zones 1/21
The weighing platforms are available with an analog scales interface or a digital IDNet scales
interface.
Information about the maintenance, troubleshooting and repairs are contained in the Service
Manual ME-22014210.
2 Safety instructions
2.1 Safety instructions for PUA574 (coated)
▲ Do not use the weighing platform in hazardous areas!
2.2 Safety instructions for PUA579(x) (stainless)
There is an increased risk of injury and damage when the weighing platforms
are used in hazardous areas! Special care must be taken when working in
such hazardous areas. The rules for behaviour are based on the concept of
"Safe Distribution" established by METTLER TOLEDO.
Competence
▲ The weighing platforms PUA579(x) may only be installed, maintained and repaired by
authorised METTLER TOLEDO service personnel.
Ex approval
▲ No modifications may be made to the device and no repair work may be performed on the
modules. Any weighing cells or system modules that are used must comply with the
specifications contained in the installation instructions. Non-compliant equipment
jeopardises the intrinsic safety of the system, cancels the Ex approval and renders any
warranty or product liability claims null and void.
▲ The safety of the weighing system is only guaranteed when the weighing system is
operated, installed and maintained in accordance with the respective instructions.
4
▲ Also comply with the following:
– the instructions for the system modules and weighing cells
– the regulations and standards in the respective country
– the applicable statutory requirements for electrical equipment installed in hazardous
atmospheres in the respective country
– all instructions related to safety issued by the owner
▲ The explosion-protected weighing system must be checked to ensure compliance with the
requirements for safety before being put into service for the first time, following any service
work and every 3 years, at least.
Operation
▲ Prevent the build-up of static electricity. Always wear suitable working clothes when
operating or performing service work in a hazardous area.
▲ Do not use protective coverings for the devices.
▲ Avoid damage to the system components.
Installation
▲ Only install and perform maintenance work on the weighing system in the hazardous areas
if the following conditions are fulfilled
– if the intrinsically safe characteristic values and zone approval of the individual
components are in accord with one another
– the owner has issued a permit ("spark permit" or "fire permit")
– the area has been rendered safe and the owner's safety co-ordinator has confirmed that
there is no danger
– the necessary tools and any required protective clothing are provided (danger of the
build-up of static electricity)
▲ The certification papers (certificates, manufacturer’s declarations) must be present.
▲ Lay cables in such a way that they are protected from damage.
▲ Only route cables into the housing of the system modules via the suitable cable coupler
and ensure proper seating of the seals.
Additional requirements for Category 3 (Zone 2/22)
▲ The explosion-protected weighing platform PUA579 may only be operated in Zone 2 and
22 hazardous areas in conjunction with weighing terminals that have a corresponding
approval and interface specification.
▲ The connection cable may not be separated from the weighing terminal while it is
energised.
▲ Tighten the knurled nut of the IDNet connecting cable with 10 Nm.
5
3 Selecting the installation location
▲ The foundation at the installation location
must be capable of safely support the
weight of the weighing platform at its
support points when it carries the
maximum load. At the same time it
should be so stable that no vibrations
arise during weighing work. These
requirements also apply when the
weighing platform is integrated in
conveying systems and the like.
▲ Ensure that vibrations from machines
near the installation site are kept to a
minimum.
Ambient conditions PUA574 (coated)
➜ Use the weighing platform only in a dry environment.
Ambient conditions PUA579(x) (stainless)
➜ Use the weighing platform in a dry environment or in a humid environment.
4 Equipotential bonding (for categories 2/3)
The equipotential bonding must be installed by a professional electrician when using the
weighing platforms PUA579(x) in hazardous areas. METTLER TOLEDO Service only has a
monitoring and consulting function here.
The equipotential bonding terminal is positioned at the terminal box of the weighing platform.
➜ Connect equipotential bonding (PA) of all devices (weighing platform, service terminal)
in accordance with the country-specific regulations and standards. In the process, make
sure that all device housings are connected to the same potential via the PA terminals.

6 Setting up
Note
For a verifiable application the weighing platform has to be fastened to the floor as shown
with access ramp(s) and/or base plates or with the installation frame.
For a non-verifiable application the weighing platform can also be operated without fastening
to the floor with access ramp(s) and/or base plates or with the installation frame.
6.1 Above-ground installation with access ramp or base plates
➜ Place access ramp(s) and/or base
plates on the even floor in front of and
behind the weighing platform at a
suitable location.
➜ Lift the weighing platform at the handles
and place it with the levelling feet into
the provided recesses of the ramps or
base plates.
or
➜ Ensure levelness in the area of the
scales bases. If applicable, level using
adjustable levelling feet.
or
➜ Align the ramps and base plates.
➜ Mark the position of the ramps and
base plates and dowel them into the
floor using the supplied dowels
(2 dowels each per ramp or base
plate).
➜ Set the screws for vibration limitation at
the base plates to 2–3 mm play.

6.2 Above-floor installation with installation frame
In non-verification operation
Note
This installation is only suitable for use with hand pallet trucks or roll containers. Other uses
may cause the weighing platform to be displaced.
➜ Apply the anti-slip rubbers to the bottom
of the installation frame. Ensure that the
ground is clean and free of oil.
➜ Assemble the installation frame as
shown in the enclosed assembly
instructions.
➜ Set up the installation frame at a suitable location with a level ground.
➜ Insert the weighing platform in the
installation frame and level using the
adjustable levelling feet.
➜ If appropriate, place the ramp(s) on.
➜ If you use a ramp, set the screw for
vibration limitation to 2–3 mm play.

8 Operating limits
The weighing platforms are designed
extremely robustly. However, the load limits
in the following table should not be
exceeded.
Depending on the type of load bearing, the
static bearing, i.e. the maximum permissible
load, amounts to:

➜ Avoid falling loads, shock loads as well
as impacts from the side.
Operation with access ramps
• The load plate of the weighing platform is an active weighing component. The access
ramps are passive. This means that during the weighing process all the wheels of the
transport vehicles have to be on the load plate.
• The air gap between the load plate and the access ramps has to be free. The gap should
therefore be inspected regularly and kept free, in particular during the weighing of granular
or small-scale material.
